JOINT FOR SASI-I-ZBARS.

Application filed July 28, 1913.

To all u'hom 'zizmag concern:

Be it known that I, JOAI-I Buoennn, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Joints tor Sash-Bars, whereof the following is a specification, reference being had to the accompanying drawings.

The invention relates more particularly to metal sash bars which are made by dividing one of said bars in sections and provid ing the ends of the sections with pro ecting parts which are adapted to extend through a mortise formed in the tongue of the other bar.

An object of the invention is to provide a sectional sash bar which may be cheaply made, and which sections, when assembled, are firmly held together, thus making up a strong and durable metal sash.

In the accompanying drawings, which show one embodiment of the invention, Figure I, is a plan view of a section of a metal sash embodying the improvement.

Fig. II, is a transverse sectional view on the line II, II, of Fig. I.

Fig. III, is a transverse sectional view on the line III, III, of Fig. II.

Fig. IV, is a sectional view on the line IV, IV, of Fig. II.

Fig. V, is a perspective view of the end of one section of the divided bar.

Fig. VI is a perspective view of the end of the other section of the divided bar.

In carrying out the invention, one sash bar is provided with a tongue mortised at the point where the other sash bar is to be joined and cross the first sash bar. The other sash bar is divided transversely so as to form abutting ends, adapted to rest against the side faces of the tongue of the first sash bar, and with projecting portions adapted to pass through the mortise in the tongue. These projecting port-1ons l1e in the same plane and are of the full thickness of the tongue of the sash bar. The projecting portions are so spaced that one lies above the other when they are projecting through the mortise in the tongue of the other bar. Each projecting portion of the divided sash bar is formed with interlocking means, whereby two sections may be firmly secured together.

Referring more in detail to the drawings, the sash bar 1, is provided with a tongue 2,

having a mortise 8, extending therethrough. The other sash bar is divided so as 'to form two sections a, and 5. The upper portions of the sections are formed as in the usual manner, so as to properly join the upper portion of the other sash bar. The end of the divided section 5-, is formed with an abutting portion 6, adapted to engage the side face of the tongue 2, of the sash bar 1, while the end of the section 5, is provided with an abutting portion 7, which engages the other face of the tongue 2. The section 1, is also provided with a projecting portion 8, while the section 5, is formed with a projecting portion 9. These two projecting portions are of the full thickness of the tongue, and are so disposed that one passes through the mortise 3, above the other. The

end of the section 1, iscut away as at 10, to receive the projecting portion 9, on the section 5. The section 5, is formed with semicircular recesses 11, and 12, which are adapted to register with semi-circular recesses 13, and 14C, respectively formed in the projecting portion 10. When the two sections 1, and 5, are properly assembled with the proj ecting portions extending through the m0rtise 3, rivets 15, are passed through the registering recesses 11, 13, and 12, 1 1, and these rivets serve to hold the projecting portions "from being withdrawn from the mortise in the sash bar 1.

From the above construction it will be apparent that I have provided a metal sash bar which may be readily rolled and formed, and. therefore, cheaply made. When the sections of the divided sash bar are in place and secured together, I have a very durable metal Sash bar.

It is obvious that minor changes in the details of construction and the arrangement 0t parts may be made without departing from the spirit of the invention, as set forth in the appended claims.

Having thus described my invention, I claim:

1. A joint for metal sashes comprising crossing bars, one of which has a mortised tongue, and the other of which is divided transversely, forming sections, the end of each section having a portion adapted to abut against the side faces of the tongue of the other cross bar, and a projecting portion extending through said mortise, said projecting portions being the full thickness of the tongue of the sash bar, and lying one over the other and filling said mortise, the adjacent faces of said projections having registering recesses adapted to receive looking members for holding said sections together and in assembled relation with the other cross bar.

2. A joint for metal sashes comprising cross bars one of which has a mortised tongue, the mortise being located at a point above the lower edge of the tongue and the othei of which is divided transversely forming sections the end of each section having a portion adapted to abut against the side faces of the tongue of the other cross bar below the mortise, said projecting portions being the full thickness of the tongue of the sash bar and lying one over the other in and filling said mortise, the adjacent faces of said projections having spaced registering 20 recesses adapted to receive locking rivets for holding said sections together and in assembled relation with the other cross bar.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsyl- 25 Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents Washington, D. G.
